Missing Algorithm: AES-KW about webcrypto HOT 7 CLOSED

Can you explain the approach you would take? In particular for the crypto algorithm implementation itself.

from webcrypto.

So far as I understand, webcrypto-core covers most of the input validation and routing to the providers. I already got import/export working easily by creating a new provider.

As for the algorithm itself, I am certain NodeJS already supports AES-KW via crypto.createDecipheriv. I know that the cipher name via OSSL is id-aesXXX-wrap (where XXX is the key size) with IV of A6A6A6A6A6A6A6A6 hex.

I also have the RFC to work through given known test vectors via https://tools.ietf.org/html/rfc3394

You can track my progress with this PR: https://github.com/LiraNuna/webcrypto/pull/1

@LiraNuna I've updated webcrypto a bit. Please sync you code with the latest version.
You can use wrappedKey test param for AES-KW wrapped key checking (example)

@LiraNuna If your PR is done, I can accept it and publish new version to npm

Is that the binary of the 'expected encrypted key'?

from webcrypto.

yes

Just updated PR #5 with 3 of the test vectors from RFC 3394.
